Figure 4. I/O connector pin-out
The analog outputs of the CIO-DDA06/JR are two-wire hook-ups. Always use low-level ground (LLGND) as
the ground reference for all analog hook-ups. The output range of the CIO-DDA06/JR is ±5 volts and cannot be
changed. There are no trimming pots on the board so no hardware calibration is necessary or possible.
